About this Project
The Florida Department of Transportation's (FDOT) contractor has completed improving the interchange at Interstate 75 and County Road 54 (CR 54) to accommodate the future widening of CR 54 by Pasco County and to prepare for the future widening of I-75 to six lanes.
The project included the complete removal and replacement of the existing bridges at CR 54, the resurfacing of I-75 from south of State Road 56 (SR 56) to north of CR 54, and the widening of entrance and exit ramps at CR 54. It also included the construction of retention ponds, mitigation areas and storm drainage.
Detours were necessary when overhead bridge work was done over the width of the eastbound or westbound lanes on CR 54. This work included bridge demolition, placement of bridge beams, and concrete deck pours. The detours were in place during overhead bridge operations at night during off-peak hours.
The construction phasing was designed so that all existing lanes of traffic were maintained on I-75 and CR 54 during peak traffic hours.
In order to maintain the construction schedule and to minimize the impact to the public, it was necessary to perform a considerable amount of work at night. The majority of this work included asphalt paving and bridge construction operations. Lane closures were used during different phases of the project.
Lane Closure Hours
Interstate 75: 8 p.m. to 5 a.m.
County Road 54: 10 p.m. to 5 a.m.
